What to do if you have a technical problem with OJS:

1. Search the forum. You can do this from the Advanced Search Page or from our Google Custom Search, which will search the entire PKP site. If you are encountering an error, we especially recommend searching the forum for said error.

2. Check the FAQ to see if your question or error has already been resolved.

3. Post a question, but please, only after trying the above two solutions. If it's a workflow or usability question you should probably post to the OJS Editorial Support and Discussion subforum; if you have a development question, try the OJS Development subforum.

I do not know whether this problem had been addressed in the past, but here goes:

Cleaning my users lists, I found unknown users registered as section editors, editors, even as a journal manager. I tried to simulate this by registering as a new user, but I could not get beyond reviewer status. We recently move servers and we upgraded to the latest version of OJS. Can someone help me to plug this security issue?

Thank you

Hi Yoesrie,

We haven't heard of this kind of flaw; the closest I can think of is a flaw in OJS 2.0.0 through 2.0.2-1 that affected administrator validation, but I don't think there are any exploits in the wild. It's much more likely that these roles came via your upgrade path -- did you migrate from OJS 1.x? -- or things like accidental enrollments, role merges, or maybe a simple account breach through a guessed password.

It's difficult for me to ascertain what happened from here beyond auditing the code; if you're able to find out any more information, please let me know.
